BRAKE-SHOE Application filed March 9, 1908.

To all whom "it may concern:

Be it known that I, GEORGE A. WooDMAN, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Brake-Shoes, of which the following is a specification.

The object of this invention is to provide means of a simple and inexpensive character adapted to be embedded in a shoe during the casting operation for the purpose of reinforcing the body of the shoe and its attaching lug and to hold the parts together in case of fracture.

With these and other objects in view the invention contemplates, generally, a pair of strips of commercial or other iron bent to cross each other at their middle and conform substantially to the shape of the attaching lug and embedded in the shoe at or adjacent to its back during the casting operation.

In the accompanying drawings I have illus trated my invention embodied in a conventional form of composite car brake shoe and referring thereto Figure 1 is a plan view showing the shoe body and attaching lug in broken lines and the reinforcing strips in full lines. Fig. 2 is a side view showing the parts in the same manner. Fig. 3 is a detail view of one strip.

Referring to the drawings, l designates the body, 5 the attaching lug and 6 the inserts of the shoe, these parts being familiar in the art and requiring no specii'ic description. It may be noted further at this point that the invention can be applied to a variety of different patterns of shoes, both car and driver shoes, common or composite, by simply adapting it in each case to the particular construction.

The reinforcing strips 7, 8, are made, preferably, of commercial iron but they can be made in any suitable manner and of any desired material. These strips are bent upward at 9 and transversely at 10 to cross each other like the letter A at the top of the attaching lug 5. One of the transverse parts 10 is upset to form a depression 10 to receive the transverse part 10 of the other strip. The strips are embedded in the body of the shoe at or adjacent to its back, the upright parts 9 are embedded in the sides of the attaching lug and the transverse parts 10 are embedded in the top of the attaching lug. The strips will reinforce the body and the attaching lug of the shoe and hold the parts to- Specification of Letters Patent.

gether in case of fracture. If the cast part 5 of the attaching lug is removed the strips will answer the purpose of an attaching lug, and for this reason the shoe may be made with the strips forming the attacl'iing lug, without any of the cast iron thereon.

For the purpose of preventing the end parts of the shoe from slipping off the strips in event of a fracture I prefer to arrange the strips out of parallel relation to each other. This can be done by shaping the strips to diverge at the ends or to converge or one strip may be laid at an inclination towards or from the other strip, the pur pose in each case being to provide a wedgelike action between the strips and the body metal in the event that there is not a union of these parts in the manufacture thereof to lock the parts together in case of fracture.

What I claim and desire to secure by Letters Patent is:

1. A reinforcement for a brake shoe con sisting of two strips bent between their ends transversely of their length and crossing each other.

2. A reinforcement for a brake shoe consisting of two strips extending lengthwise of the shoe side by side and bent upward and transversely to cross each other between the ends of the strips.

3. A reinforcement for a brake shoe consisting of two strips extending lengthwise of the shoe side by side and bent to cross each other between their ends and form the at taching lug of the shoe.

4. In a brake shoe, the combination with a body and an attaching lug thereon, of two strips embedded in the body at or adjacent to its back and bent to cross each other and pmbedded at the crossing in the attaching 5. In a brake shoe, the combination with a body and an attaching lug thereon, of two strips embedded in the body at or adjacent to its back and bent upward away from the body and transversely to cross each other between their ends, the upright and cross parts of said strips being embedded in the attaching lug.

6. In a brake shoe, the combination of a body, and two strips bent between their ends transversely of their length and crossing each other, said strips being embedded in the body at or adjacent to its back, that part of each strip on one side of the transverse part lying adjacent to one side of the body and that part of each strip on the opposite side of the transverse part lying adjacent to the other side of the body.

7. In a brake shoe, the combination of a body, and two strips bent between their ends transversely of their length and crossing each other, said'strips being embedded in the body at or adjacent to its back, that part of each strip on one side of the transverse part lying adjacent to one side of the body and that part of each strip on the opposite side of the transverse part lying adjacent to the other side of the body, and the parts of both strips on each side of the crossed parts being in clined in opposite directions.

embedded in the sides and top of the attach- 25 ing lug.
